NOTES
1 Under steady-state (non-transient) conditions I
2 Capacitive loading on ports 0 and 2 may cause spurious noise pulses above 0 4V on the low-level outputs of ALE and

greater than the listed test conditions
ports 1 2 and 3 The noise is due to external bus capacitance discharging into the port 0 and port 2 pins when these
pins change from high to low In applications where capacitive loading exceeds 100 pF the noise pulses on these
signals may exceed 0 8V It may be desirable to qualify ALE or other signals with a Schmitt trigger or CMOS-level input
